Is There Something to Put on Concrete to Stop It From Getting Too Hot?

A cool deck around your pool protects your feet.

Although a concrete surface is durable and long-lasting, in climates with torrid summer sun, patios and pool decks can become too hot to walk on comfortably. If you're looking for a cool, slip-resistant surface, try a concrete overlay, spray or deck-cooling option, all of which are durable and require little maintenance.


Concrete patios and pool decks offer homeowners an inexpensive, durable, low-maintenance option for foot traffic areas. Your design layout options are unlimited with concrete, since it can be poured into nearly any shape or pattern. Although the dull, gray color of concrete lacks visual appeal, concrete surfacing options are available to create a decorative appearance for your patio or pool deck while giving you a cool walking surface.

Kool Deck

Kool Deck, a trademarked product manufactured by Mortex Manufacturing, is designed for use in foot traffic areas such as pool decks, walkways and patios. Kool Deck is a strong, textured cement surface that lowers the surface temperature of concrete. Blended with concrete or applied to finished concrete, the product is resistant to stains, mold and mildew.

Concrete Overlays

Concrete overlays are a polymer-modified cement product that's suitable for patios, porches, walkways and pool decks. The product is sprayed on in a thin coat and troweled to create a slip-resistant, textured surface. The choice of textures and designs resemble tile, slate, flagstone or brick. The surface is cooler than concrete or aggregate; for the coolest surface, choose a light color. Concrete overlays are durable and mildew-resistant. The surface, although textured, is not rough and won't hurt bare feet or damage clothing if you sit on it.

Acrylic Sprays

Acrylic sprays are available in a wide range of colors to give a decorative finish to your porch, pool deck or patio. Textures and patterns are added after the acrylic spray is applied. The surface repels water and resists staining from grease and oil. Acrylic sprays provide a surface that's cooler to the touch than plain concrete.
